What direct control of the panzer divisions might have changed

Could D-Day have been reversed if Rommel had direct control of the panzer divisions and released them earlier?

It would have made the landing more dangerous, but the armour still had to move through an Allied-dominated air environment and disrupted transport network.

Rommel's direct control could have accelerated an armoured response and made rapid linkage between the beaches even more urgent. The same movement would expose tanks and supply columns to Allied aircraft, while Special Operations Executive activity could further delay their routes. An earlier release would have complicated the landing without guaranteeing a German victory.
